'Sandal' in the Bible

He kept proclaiming, "The one who is coming after me is stronger than I am, and I am not worthy to bend down and untie his sandal straps.

John replied to all of them, "I'm baptizing you with water, but one is coming who is more powerful than I, and I'm not worthy to untie his sandal straps. It is he who will baptize you with the Holy Spirit and fire.

He is the One coming after me, whose sandal strap I’m not worthy to untie.”

and the Lord said to him, Loose the sandal of thy feet, for the place in which thou hast stood is holy ground;

and as John was fulfilling the course, he said, Whom me do ye suppose to be? I am not he, but, lo, he doth come after me, of whom I am not worthy to loose the sandal of his feet.
